lol My thought is on nights when I want to run lights and troll banks I would toss the little DC genny in the boat. on normal nights when I am chasing bigheads I will just run my troller on 2 batterys .. it lasts all night. for me a little genny like this would save a TON of money and weight on my 1448. you can build the whole thing for around $200 and it weighs about 35 -40 lbs. The 3.5 predator motor is more than enough to run it.op: I'm waiting for you gear heads and electricians to chime in. Simple was bringing 2 sets of batts and change them out when went dead very simple now had to go and get all technical lol
That's been done before and don't work as well as you would think. 1 downfall is just safety. They belt would literally ride next to the prop. If it jumps u just bought a new prop and who knows what else. 2, it just robs to much hp from the fan and changes everything as far as the fan performance.The more I think about your dc charger, the more I like the idea. I'm betting guys with fans could fix both the homemade generator and their fan up for quick disconnect and installation of a single alternator so it can be swapped between the two cause the good ones ain't cheap! No buying converters..no buying 2 to 3 grand of inverter generator/s...and a single charging system with its peripheral components such as switches, isolators, meters, etc. within the boat. Nice!
I'd say go for it. That's no different than what I run on my airboat. I got a 140 amp alternator (while running above 1000 rpm and 80 amp at idle) running 10-50w, 2- 30w and 2-10w floods at the same time. But that little engine will stay at wot all the time so that shouldn't matter. All off of one battery also. I wouldn't see a need of 2 batteries personally.
